GS Telescope shutdown on February 21st due to P2WFS repairs
It has been found after extensive troubleshooting that the Peripheral Wave Front Sensor 2 (P2WFS) has a mechanical issue and is out of order. To address this issue the P2WFS will have to be replaced in the telescope by a dummy unit while it is being repaired. We are planning for this intervention starting Monday February 21st and the removal and installation of the dummy unit will take two days and thus the telescope will not be available from the Night February 21st to 22nd.
